Any unencrypted HTTP (“http://…”) connection has the same problem. Yet
the same browsers don't present a big scary warning for those?

The flaw in the browser is that it doesn't complain when an unencrypted
HTTP connection is established, but only complains when an *encrypted*
connection is made to a site with a self-signed certificate.

Right. By that logic, let's advocate for browsers to present a big
intrusive warning for every HTTP connection that has no SSL layer or
certificate.

I will agree that a self-signed certificate presents the problem of how
to verify the certificate automatically.

Where I disagree is that this is somehow less secure than a completely
*unencrypted* HTTP connection. No, the opposite is true.
